BEAM DYEING MACHINE.

Be it, known that EUGENr. HoL'r and Larern'inrr. Hour, citizens of the United States, residing at Burlington, in the county of Alamance'and State of North Carolina,

have invented certainnew and useful Improvements in Beam Dyeing-Machines, of

which the following'is a specification;

. The object of the invention-is to provide ing or boiling bleaching, dyeing, oxidizing an apparatus for the treatment of yarns and similar materials in the operation'of cleanor fixing, developing, etc., of the type known in the art as beam dyeing machines, wherein increased efficiency may be attainable,

particularly in the matter of uniform ap'plication ofthe-treatment to all portions of the fibers exposed, so that uniformity of the product, especially in color or tone, may be 0 secured, and in the matter of preventing premature oxidation or fixlng whil insur- 111g uniform oxidation and development at tha proper stage in the procedure,and atthe same time to attain this ObjGCl; by aneconomical use of the dye liquors, steamiand other chemicals and agents employed n this connection.

A further object of the invention is to provide an apparatus of the class indicated, wherein precipitation or stratification of the dyeing agents or other chemicals held in suspension in the treating fluid, may be prevented, and wherein the direction of appl cation of the treating fluid to the material may be varied tosuit the conditions and characteristics of such material.

' With these and other objects in view, the invention consists in a construction and combination of parts, of which a preferred embodiment is illustrated in the drawing and is hereinafter specifically describ'ed', it being understood that various changes in the form, proportion and minor details of construction and arrangement may he re-' sorted to, without departing from the spirit of the invention.

' beam comprising upper and lower heads and 14 connected by a hollow" bar el, 1 r

which is perforated or ported,"orjis ,of ticulated or open construction to -perni" of lateral circulation, either inwardly onoutward-ly therethrough' in the course of operation, as hereinafter described. Thisjbarrel is closed at its upper end, as shown iatlti, and is open at its'lower end for communication with a port 17 formed, as illustrated, in the base or bottom of the vat,"the beam being centered at'its lower end in the vat by means of downwardly convergent guides" 18 aud being fitted steam-tight upon the seat. 19 at the bottom of the vat around .theport 17, to insure communication only between the port and the interior of the barrel when,

the beam is in place; This s'team tightseafl ing of the beam is insured by means' of a set screw 20 bearing upon the upper end ofza center or core rod 21 in-the beam and threaded in a cross bar 22, whichbears against the under surface of the topor upper walljof the vat. Q, v The vat is sealed at the top by means of a lid or cover 23 held in. place by any suitable means, such as the pivotal lockingbolts;

24-, and hand Wheel nuts 25.

In communication (by meanshereinafter described) with the main vat or receptacle and preferably surrounding the's'ame,.as

illustrated in the drawings, is a circulating tank 526 acting in the nature of a acket' and servmgyby reason of its COIllLQ-IltStOiiHlillH tain the desired temperature in. the main vat or receptacle, and provided with-a relief port or vent 27 which may be valved, as shown at 28. Also an overflow is provided, as shown at 29, from the main vat or ref ceptacle into the circulating tank, saidovr flow being provided'with a controlling and regulating valve 80, and in communication with the interior of the vat and extending, as shown, through the circulating tankjis a pressure gage-31, which alsoserves windicate the level of the surface of the i'e quired contents of the vat.

In coiiperation with the receptacles above described, there is employed a circulating "its system for fluid, whether hot water, dyeing liquor, or other chemical or agent, air, steam, or a combination of any two or more there. of, designed to induce a circulation of such fluid for the purpose, primarily, of th0roughly saturating or impregnating the-material within the vat, and arranged, for example, on the beam or holder, and adapted to be reversed indirection, so that the fluid ma be forced or carried through the materia on the beam or holder in either direction radially of the beam and also designed, secondarily, to maintain the liquor in the desired condition as to efliciencyby maintaining an agitation sufficient to prevent precipitation or stratification when there are practically solid substances held either in suspension or solution. In the preferred embodiment of the invention, as applied to this circulating system, there is employed an inlet pipe 32 which may lead from any source of supply and which communicates with the main circulating pipes 33, 34 and 35, the pipes 34 and 35 being connected transversely by branch pipes 36, 37 and 38, which are respectively in communication by suitable ports 39, 40 and 17, in the bottom of the receptacle structure, the port 39 communicating with the circulating or mixing tank, the port 40 with the main receptacle or vat exterior-1y of the beam, and the port "17, as hereinbefore described, in communication with the interior of the vat within the hollow barrel of the beam. In addition to the foregoing, there is a branch pipe 41 leading from the port 42 in the floor of the circulating or mixing tank 26 to the circulating pipe 35.

Located in each branch pipe for controlling communication thereof with the main circulating pipes are valves, those in the branch pipe 36 being designated respective] as 36 and 36; those in the branch pipe 3 as 37 and37 those in the branch pipe 38 as 38 and 38 and that in the branch pipe 41 as 41*. Moreover, in the main circulating pipe 35 there are arranged two valves 35 and 35* located respectively on opposite sides of the point of communication of the branch pipe 41, for the purpose hereinafter explained. i i

The main pipe 35 may lead to a suitable storage tank or drain, into which the dyeing or other liquor or chemical, after use, may be withdrawn, and a valve 43 is employed to control the. outlet through that medium. In the same way, the main circulating pipe 34 may be extended to a drain or other point of discharge, the outlet in that direction being controlled by the valve 44.

Also located in the main circulating system, as for example, in the pipe 33, is arranged a force feed or circulating means, such as a pump 45. s v p From the foregoing description, it will be obvious that by inducing a flow of fluid, such as water, dyeing liquor or other chetni' cal or agent for coloring, bleaching or otherwise, through the main circulating pipes, after suitably adjusting thecontrolvalvas a cireulatiomof the fluid may be produced through the beam and through the material, such as yarn on the beam, either from the interior thereof radially outward or from.

the exterior thereof radially inward, so as to permeate said material thorou hly, and by disposing the ports forming t e means of communication between the circulating branch pipes and the interiors of the receptacles in an inclined position, as shown more particularly in detail in Fig. 3, a circulatory or swirling movement of the fluid or liquor may be produced. For example, assuming that the pump is operating in a direction to induce a flow of the liquid in the direction indicated by the arrows in Figs. 1 and 2, valves 38" and 37*, 35 and 35 being open, the other valves being closed, the circulation will be into the interior of the beam outwardly through the walls of the barrel and the material warped or wound thereon to the exterior of the beam, and thence back into the system, and this continuous circulation may be maintained for any required length of time and under any desired pressure. On the other hand, if the valves 38 and 37 closed, and valves 37 and 38 are openediithe direction of the circulation will be to the vat exteriorly of the beam, thence through the yarn or'material'supported by the beam, and into the interior of the latter, and then through branch pipe 38 to the main pipe 35 and back to the pump. As hereinbefore indicated, the 'pur-- pose of the mixing or circulating tank 26 is to provide an additional means for mixing and maintaining the liquor in the proper condition to treat the yarn, and when it is desired to direct the current of material therethrough, the valve 38 may be opened to communicate with the interior of the beam, valve 37 may be opened to permit communication with the pipe 35, valve 35 being closed, valve 36 may be opened to permit of a return current to the tank 26,

- from whence the liquor passes around to the port 42 and thence through the branch'pipe ll (the valve 4L1 being opened) to pipe 35,

and back to the pump. Or the arrangement.

of the valves may be readjusted to reverse the direction of flow through the yarn and 1,ace,saa

It is well known that in order to properly treat yarn with certain dyeing liquors, it is necessary to exclude air during the saturation or impregnation-of the material, or-du r ing the deposit of the dyeing material on. the yarn, -1I1 order to prevent oxidation. This can be accomplished by reason ofv the use of sealed vat, as already described, and after the saturation has been completed,

be introduced and circulated by the same circulating means as is described above, such admission, for .example, being through a valved inlet pipe 47, and in orderto main; tain the temperature and assist in the oxidation and fixing of the dye, steam may also be introduced, as through a valved steam inlet. pipe 48.

possible not only to insure a thorough and uniform application of the cleansing, dyeing or bleaching agent to the material being treated, by producing a forced circulation thereof through said material," either outwardly or inwardly in' aradial direction and reverse said direction as may be necessary to accomplish the desired object, but to subsequently subject said material to a similar circulation in either direction, of an oxidizing or other fluid, for the purpose of fixing and developing the color, the direction of flow being controlled by the adjustment of the valves which also permit of entirely withdrawing the liquor or other agent from the apparatus when it has performed its function, and when it is desired either to substitute another agent or to permit of removing the beam from the vat.

It will be apparent, moreover, tery of vats may be operated in connection with a single circulatory system, as indicated, and that a plurality of beams may be arranged in a single vat.
